At Nick's 6 year well check (that we did a few months late) the pediatrician noticed that his heart skips a beat. He ordered an EKG to check it out and make sure there weren't any serious problems.
The tech that did his EKG was awesome and let all 5 of us come in the room to watch. She showed all the kids how to attach the electrodes and they got Nick all hooked up. We all watched on the monitor and saw his heartbeats: blip. blip. blip. nothing. blip. blip. blip. nothing. Luckily they said that it wasn't anything serious and they'll just keep an eye on it.
